James is usually the big spoon, but sometimes Regulus tries his best to be, because he wants James to feel as loved as he does. He’s just clinging to James, head on James’ back, his feet not remotely close to James’ under the covers because of height difference.
James will sing songs absentmindedly, regardless of what he’s doing. Regulus has picked up the habit, and you can find him humming or mumble singing as he studies
Regulus has a bunch of issues with marriage/children, and doesn’t think he wants them until he’s with James, and he realizes how much he loves James, and how much he wants that with him.
They shower together. Almost always.
James cooks, Regulus bakes. Whoever’s not using the kitchen is sitting on the counter talking about their day while the other cooks/bakes.
(Kinda NSFW ‼️) James is the top in sex, but when they cuddle, James pulls Regulus on top of him, no question.
(DEF NSFW) Regulus reads the dirtiest smut books and, ahem, recreates them with James.
Regulus has a sun tattooed on his shoulder blade, James has the Leo constellation, with the Regulus star specifically highlighted, on his shoulder
Barty was Regulus’ best man. When Sirius asked why Regulus didn’t ask him, he innocently said “You’ll be James’ best man. But you’ll walk me down the aisle.” Sirius sobbed.
James was so nervous about proposing, his dropped the ring. Regulus knelt down to help him as he fumbled with it, and they ended up on their knees in front of each other, both their hands clasped around the ring and dramatically staring into each other’s eyes.
